TrustFlow SDK Architecture

Module Structure

src/
├── types/          # Core TypeScript interfaces
├── escrow/         # Escrow client, builder, monitor, dispute
├── auth/           # Challenge-sign auth flow
├── stellar/        # Network config, account, transaction helpers
└── utils/          # Validation, formatting, retry, error, logger

Design Principles

  1. Result types — SDKResult<T> avoids thrown exceptions in public APIs
  2. Immutable builders — EscrowBuilder produces validated EscrowParams
  3. Network agnostic — all clients accept StellarNetwork enum
  4. No side effects — utilities are pure functions
